The structural part in direct contact with the cast-in-place concrete and controlling the predetermined size, shape and position is called formwork. Therefore, the cleanliness of the formwork surface and the spraying state of the release agent will directly affect the appearance quality of the newly poured concrete after demolding.

[0003] Currently, in the construction of high-rise concrete bridge towers, hydraulic climbing formwork is often used. After the formwork is dismantled, high-altitude work needs to be carried out in a narrow space to complete the cleaning of the formwork surface and the application of release agent, so as to meet the requirements of the next pouring. At present, the cleaning and application of bridge tower formwork are mainly completed by manual work. Due to the complex environment of bridge tower construction and the randomness of workers' subjective operation, the surface state of the formwork cannot be completely guaranteed to meet the requirements of concrete pouring.

When it is needed to be separated, the rudder 124 drives the cam 125 to rotate, so that the small edge of the cam 125 faces the middle plate 122, the electromagnet 126 is synchronously powered on, and the middle plate 122 is reset under the action of the spring rebound force, the cleaning head is no longer tightly pressed against the template 2, the vacuum pump is closed, and the adsorption module 12 can be separated.

[0043] The technical scheme can further include the following technical details to better achieve the technical effects: each group of adsorption modules 12 is provided with a plurality of suction cups, the plurality of suction cups are divided into a plurality of groups, the suction cups in the same group of the plurality of adsorption modules 12 are controlled by one vacuum pump, and the suction cups in different groups are controlled by different vacuum pumps. In the embodiment, two groups of adsorption modules 12 and two vacuum pumps are provided, each group of adsorption modules 12 is provided with four suction cups, the two suction cups of each adsorption module 12 are controlled by one of the vacuum pumps, and the remaining two suction cups of each adsorption module 12 are controlled by the other vacuum pump, forming alternating adsorption. If the suction cups leak due to nails or other obstacles, only part of the suction cups will be affected, and the remaining suction cups can still work normally, forming two independent systems.

[0044] The technical scheme can further include the following technical details to better achieve the technical effects: the spraying unit further includes a second scraper 13b5 arranged between the roller brush assembly and the adsorption module, the second scraper 13b5 is used for scraping water stains on the template to reduce water entering the suction cups.

[0045] The technical scheme can further include the following technical details to better achieve the technical effects: the frame 11 is connected with the electric cylinder through a connecting part 3;

[0046] As shown in Figure 5 the connecting part 3 includes:

[0047] The upper adjusting module 31 is used to solve the distance between the cleaning head and the template 2, and comprises a first frame body 311, a first guide rail 312 and a first spring adjuster 313. The electric cylinder is connected with the first frame body 311, the first guide rail 312 is preferably in the form of double guide rails, the first guide rail 312 is arranged in the first frame body 311 and is perpendicular to the direction of the template 2, the first spring adjuster 313 is connected with a first sliding block 314 on the first guide rail 312, the other end of the first guide rail 312 is connected with the first frame body 311 through a first spring (not shown in the figure), and the first spring adjuster 313 is used to adjust the position of the first sliding block 314 on the first guide rail. The structure of the first spring adjuster 313 comprises a fixed plate, a bolt, a limiting sleeve, a pair of nuts, a clamping piece and a second spring. The fixed plate is connected with the first frame body 311, the limiting sleeve is fixed on the fixed plate, the bolt is screwed on the limiting sleeve, the clamping piece is limited by the pair of nuts on the bolt, one end of the second spring is connected with the clamping piece, and the other end of the second spring is connected with the first sliding block 314. The tension of the second spring is adjusted through the rotation of the bolt, so that the first sliding block 314 moves forward and backward, and the distance between the cleaning head 1 and the template 2 is adjusted.

[0048] The middle adjusting module 32 comprises a second frame body 321, a third frame body 322 and a spring buffer hinge 323. The second frame body 321 is connected with the first sliding block 314, the third frame body 322 is arranged below the second frame body 321, the third frame body 322 is hingedly connected with the second frame body 321 through a bolt, and the spring buffer hinge 323 is connected with the second frame body 321 and the third frame body 322 respectively. The spring buffer hinge 323 is arranged to enable the cleaning head 1 to rotate by a certain angle in the vertical plane perpendicular to the template 2, so as to adapt to the distance between the cleaning head 1 and the template 2.

[0049] The middle adjusting module 32 further comprises a first limiting screw 324 arranged on one side of the second frame body 321. The angle of rotation of the cleaning head 1 driven by the spring buffer hinge 323 is adjusted by adjusting the first limiting screw 324. When the first limiting screw 324 abuts against the spring buffer hinge 323, the maximum rotation angle is reached. The middle adjusting module 32 further comprises a second spring adjuster 325, which has the same structure as the first spring adjuster 313. The second spring adjuster 325 is arranged on both sides of the third frame body 322 and is connected with the third frame body 322 through a spring. The other end of the second spring adjuster 325 is connected with the second frame body 321 / the first frame body 311 (the spring in the second spring adjuster 325 connected with the first frame body 311 is not shown in the figure). The stability of the rotation of the third frame body 322 is ensured by the pulling force of the spring of the second spring adjuster 325.

[0050] The lower adjustment module 33 includes a fourth frame 331, a fifth frame 332, and a bearing 333; the fourth frame 331 is fixed to the third frame 322, and the fourth frame 331 and the fifth frame 332 are connected by the bearing 333, which enables rotation of the two relative horizontal planes; the fifth frame 332 is connected to the frame 11.

[0051] The lower adjustment module 33 also includes a second limiting screw 334, which is disposed on the fourth frame 331. By rotating the second limiting screw 334, the distance between the second limiting screw 334 and the fifth frame 332 is adjusted, thereby adjusting the horizontal rotation range of the fourth frame 331 relative to the fifth frame 332.

[0052] The cleaning head can be connected to a connecting mechanism (steel wire rope, electric cylinder or other device). Since the distance between the connecting mechanism and the template 2 cannot be precisely adjusted to ensure that the cleaning head can fit precisely with the template, and the cleaning head 1 and the template 2 are not completely parallel and have a slight angle, fine adjustment can be made through the connecting part 3 to adapt to the angle and ensure the fit between the cleaning head 1 and the template 2. It can provide the same positive pressure for uneven surfaces, realize the adaptive adjustment of the three degrees of freedom of the cleaning head 1, and at the same time ensure that the cleaning head 1 is subjected to uniform force and extend the service life of the cleaning head 1.

[0053] This technical solution may also include the following technical details to better achieve the technical effect: the cleaning module 13 also includes a recycling bin 13a, the bottom of which is located below the roller brush 13b3, and the recycling bin 13a has a slag discharge hole.

[0054] This technical solution may also include the following technical details to better achieve the technical effect: such as Figure 8 As shown, the first scraper blade, used for scraping cement, includes a first blade holder 51, a sub-frame 56, a T-shaped connecting plate 52, a rigid scraper 53, a hinge 54, and a pin. The bottom of the first blade holder 51 is connected to the rigid scraper 53, and the upper part of the first blade holder 51 is connected to the sub-frame 56 through the T-shaped connecting plate 52. The sub-frame 56 is rotatably connected to the frame through the hinge 54. The end of the sub-frame 56 is provided with a pin hole 55, and a pin is detachably installed in the pin hole 55. When the pin is installed in the pin hole 55, the pin restricts the rotation of the first blade holder 51.

[0055] In the working state, the pin is inserted into the pin hole 55, preventing the hinge 54 from rotating and allowing the scraper to perform scraping operations. In the non-working state, the pin is pulled out, and the hinge 54 is rotated to drive the first blade holder 51 to rotate until the scraper disengages from the template. The inserted pin then locks the sub-frame 56, preventing it from rotating downwards and thus disengaging from the template.

[0056] like Figure 9As shown, the second scraper, used for scraping water, includes a tension spring 57, a rubber scraper, a second blade holder 58, and an adjusting block 59. The rubber scraper is installed at the bottom of the second blade holder 58. Multiple tension springs 57 are spaced apart on the top of the second blade holder 58 and are connected to the frame 11. The rotating shafts 60 at both ends of the second blade holder 58 are connected to the adjusting block 59, which is also connected to the frame 11. When in contact with the template, the template compresses the rubber scraper, causing it to rotate. The tension springs 57 apply tension to pull it back, scraping water to prevent excessive water from entering the adsorption plate.

[0057] It should be noted that the cleaning device of this application can be applied to cleaning in other related fields besides templates. The device is equipped with a walking mechanism, which allows it to walk and clean on a plane, and can also be used for vertical hanging cleaning.

[0058] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
